Value Collection USFW0880025OZ Uss Flat Washer 7/8 in

Product Description

The VALUE COLLECTION USFW0880025OZ is a USS-pattern flat washer designed for general-purpose fastening applications in trade and industrial settings. Manufactured from Grade 2 steel with a zinc-plated finish, this washer provides a broad bearing surface that distributes clamp load and reduces the risk of fastener pull-through. The USS series uses a larger outer diameter relative to screw size compared to SAE-pattern washers, making it well suited for softer base materials and oversized holes. At 0.1719 inches thick, it offers reliable rigidity without adding unnecessary stack height. Plumbers, electricians, HVAC technicians, and general contractors reach for USS washers when assembling equipment mounts, pipe hangers, and structural connections.

This washer fits a 7/8-inch screw with a 0.9375-inch inside diameter and a 2.2500-inch outside diameter. The zinc coating resists light surface corrosion in typical indoor and sheltered outdoor environments, making it appropriate for residential and light commercial mechanical rooms, electrical panels, and equipment pads. The minimum order quantity is 25 pieces per order, and washers ship as a single package quantity, keeping jobsite inventory organized.

Key Features

• USS-pattern geometry provides a wider bearing surface than SAE flat washers of equivalent screw size
• Grade 2 steel construction delivers consistent hardness for standard load-bearing fastening
• Zinc-plated finish offers corrosion resistance in dry to moderately humid environments
• Inside diameter of 0.9375 inches fits standard 7/8-inch fasteners with appropriate clearance
• Outside diameter of 2.2500 inches distributes load across a broad contact area
• Thickness of 0.1719 inches maintains stack integrity without excessive buildup

Compatibility

Designed as a standard USS-pattern flat washer for use with 7/8-inch screws and bolts in general mechanical, plumbing, electrical, and HVAC fastening applications.

Installation Notes

Installation requires no special tools beyond a standard wrench or socket set appropriate to the fastener being used. Always ensure the washer is seated flat against the mating surface before torquing the fastener. In applications subject to vibration, a lock washer or thread-locking compound may be used in addition to this flat washer. Follow applicable codes such as NEC or IPC for fastener requirements in electrical or plumbing assemblies.
